The main problem is that despite the advertisement of these universities as being at UK addresses, there is nothing in the UK other than a mail forwarding address and in many cases not even that.

Dorchester University still gives 10 college terrace as an address, however this former maildrop has been private flats for some time now with no connection to the university.
The address used by Shepperton is also a fake.

If there is no-one in the UK to take action against then we are then into a complicated tangle of international collaborations.
